Best car-cover for indoors/outdoors

[Kes]

Hi all, my S2 roadster is off to the Goodwood revival next month to appear on a trade stand and unfortunately, I wont be there (it's a long story) Anyway, I need a good quality cover that can be put over the car quickly in the inevitable event of a shower and also to prevent any more dust than is necessary settling on it. So I need something that won't scratch the paint or chrome and at least showerproof. Any suggestions?
Ta.

I'm also interested to know if someone has a good advice on this.
I actually have an indoor car-cover, but it makes micro-scratches on the new paint. I guess a MicroFiber one would probably not affect the paint.
The best then would be a waterproof car-cover, with the inside made of microfiber cloth.

There has been much discussion on this subject in the forum. I was looking into the subject but was warned that indoor covers can cause micro-blistering in the paintwork and the best option is no cover at all.
